Nadia's apartment is fantastic! I recommend it highly to anyone.
It is very conveniently located (literally connected to Thonglor station by an above-ground walkway), the beds in each bedroom were very comfortable, the showers in both bathrooms had good water pressure even at hot temperature, the air-conditioning in each room worked perfectly (without blowing directly onto the bed, which I find very important), and the washer-drier was modern, clean and efficient.
All in all, I think this 2BR apartment is a great value, especially at this price. I would gladly stay there again during a future visit, especially since Nadia was so attentive before our arrival and even arranged to have a driver pick us up at BKK airport. Two thumbs up!
